Difficulty of this blog site

I just wanted to comment on the difficulty of grasping this website.  It seems like through out this class most of us were not able to locate each other and our professor was not able to comment on our blogs.  

Well I will give the benefit of the doubt the site and not blame it, but maybe it was the user error.  But I do feel that when I joined this site that I could just go on and start "blogging" and anyone who was following me could just post a comment.  I guess I was wrong.
